Remarks
When buffers are constructed around polygons, straight line segments approximating curved parts of the buffer are generated. These sets of line segments can be replaced with single curve segments at the end of the buffering operation, if desired. You should use a small buffer deviation (see the DensifyDeviation property for details) when requesting that curves be stitched back into the output buffers. If a curve can not accurately replace its set of approximating line segments, no replacement will occur, even if this property is true. This could be the case when unioning overlaps between multiple buffers. Additionally, the buffering algorithm will sometimes “grow” buffers in stages (for example, buffer each feature by distance/3, then again, then again) in order to avoid creating very complicated intermediate results. When that happens, curves will not appear in the final version of that buffer.
